Time Trek

The Time Trek is a 13.7 kilometer long trekking and outdoor route that starts at the Tuorla Observatory and ends at the University of Turku. The Trek passes through the cities of Kaarina and Turku and is designed for all those who are interested in the history of the Universe, Earth and Life. The Trek is designed for people of all ages, and should be interesting for the whole family. The scenery along the Trek is diverse ranging from forests, fields and parks to urban environments.

The length of the Trek, 13.7 km, is intended to reflect the Universe's age, 13.7 billion years. This can be seen along the Trek as one kilometer equals to a billion years in the age of the Universe. There are rapakivi granite boulders with brass plaques along the route marking out significant points in the history of the Universe. The plaques will briefly explain the events marking a certain period. Some of the words used on the plaque might be difficult to understand, so we recommend you take with you the free brochure, that is available on Time Trek website, that includes the map and glossary.

The Time Trek is designed so that you don't have to walk all 13.7 kilometers at once. You can familiarize yourself with the latest 1800 million years of history just in Turku. There are also places to sit down and rest, as well as cafés and restaurants along the route. These are, for your convenience, also marked on the map.

Time Trek is part of Turku 2011 program and the route is opened officially 19.5.2011. During the spring the route, the web pages and this cache series will be constructed to be ready on the opening day.

Rauhalinna

Rauhalinna mansion and its surroundings on the northern shore of Kuusisto Sound (Kuusistonsalmi) is a part of the cultural landscape in the Bay of Piikkiö (Piikkiönlahti) area. An old alley lined by linden-trees leads to the courtyard of the mansion. The wooden, two-storey main building stems from the 1840’s.

The history of Rauhalinna mansion is closely connected to that of the Armfelt family from the 1840’s to 1950’s. The Governor Johan August von Essenin bought the mansion for the Armfelts in 1848. After the death of the governor Rauhalinna was passed on to the son of Vava Armfelt, Carl M.M. Armfelt and in 1938 countess Auda Armfelt became th Rauhalinnan owner of the mansion. The countess had no children but wanted to continue with her father’s and grandfather’s agricultural heritage and in 1952 she sold the estate to the artificial insemination association. .

In the spring of 2009 the hog breeding station in Rauhalinna was laid down. Nowadays the estate belongs to Faba.

Rauhalinna park:

Rauhalinna park is located to the South-West of the mansion. The landscape and especially the vegetation of the park form a unique entity. Robust oaks and forest linden-trees grow in the park naturally, and as planted species you can find red oak, beech, white beech, macedonian pine and douglas spruce there. Rauhalinna park is a valuable nature reserve.
